Traceability is fundamental to revisit and reflect on the design narratives that describe artefact evolution. In this paper, we aim to identify what characteristics are necessary to facilitate traceability of creative design processes. For this end, we use a functional prototype to connect artefacts, design rationale, and decisions in a shared workspace. We evaluated this prototype for 15 weeks with six pairs of students engaged in a user-centered design project. Our findings show that having a lean repository of artefacts annotated with design rationale can facilitate tracking progress in different phases of the process. We found that creating a record of the participants' design work is useful to reflect on and for team agreement, ensure consistency of evolving artefacts, and help in planning future steps in the design project.","PeriodicalId":334195,"journal":{"name":"Proceedings of the 2018 ACM International Conference on Supporting Group Work","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126235698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As teams become more virtual, team identification is expected to become more important. Yet, the dimensions of virtuality such as geographic dispersion, reliance on electronic communications and diversity in team membership can undermine team identification. To better understand the impact of virtuality, the authors conducted a study with 248 employees in 55 teams to examine the complex and codependent effects of virtuality. Results indicate that although geographic dispersion and perceived differences can undermine team identification, reliance on electronic communications increases team identification and weakens the negative relationship between perceived differences and team identification.","PeriodicalId":334195,"journal":{"name":"Proceedings of the 2018 ACM International Conference on Supporting Group Work","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128897594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It creates lack of individual attention for students which resulting a higher number of dropouts in earlier school classes. Previous studies show best practices of smart technologies in the classroom. This research conducted to develop an efficient and low-cost solution to create children interaction and increasing engagement and teaching efficiency in the classroom. We developed My Class Manager; a Smartphone application for quiz and test marking, audio quiz for native language learning and performance management throughout the year. This application is for Android OS Smart phones. We conducted three evaluation tests of three classes of size 35, 40 and 45 students in a local school. It created a time-efficient learning environment and provided awesome feedback to develop more functionality in the application.

The existing theory and practice of crowdsourcing suggests that uneven task difficulty plays a crucial role to task quality. Yet, it lacks a clear identifying method to task difficulty, which hinders effective and efficient execution of micro-task crowdsourcing. This paper explores the notion of task difficulty and its influence to crowdsourcing, and presents a difficulty-based crowdsourcing method to optimize the crowdsourcing process. We firstly identify task difficulty feature based on a local estimation method in the real crowdsourcing context, followed by proposing an optimization method to improve the accuracy of results, while reducing the overall cost. We conduct a series of experimental studies to evaluate our method, which show that our difficulty-based crowdsourcing method can accurately identify the task difficulty feature, improve the quality of task performance and reduce the cost significantly, and thus demonstrate the effectiveness of task difficulty as task modeling property.","PeriodicalId":334195,"journal":{"name":"Proceedings of the 2018 ACM International Conference on Supporting Group Work","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126984218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On one hand, ISPs keep raising the investment on infrastructures to speed up the data transportation. On the other hand, users are not satisfied with the perceived quality of experience (QoE). This happens mainly due to the inflexible network flow management, where only the function of rate limiting is provided for home users in the shared network environment. In this paper, we focus on the optimization of users experience by customizing bandwidth allocation for user specified preferences while maintaining high bandwidth utilization. We introduce implicit content-aware bandwidth allocation to minimize the involvement of users on complicated network setting. By leveraging the technique of software-defined networking (SDN), a prototype of content-aware traffic scheduling, Conan, is developed to verify the effectiveness of our design. Experiments show that Conan can reduce the average task completion time of interactive applications by 30-40%. During heavy traffic load, Conan can ensure stable bandwidth for each video streaming flow and greatly reduce the average stall duration.","PeriodicalId":334195,"journal":{"name":"Proceedings of the 2018 ACM International Conference on Supporting Group Work","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133902355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, scholars have examined how people do not use social media. This paper aims to synthesize these two research areas and asks: Do regretful experiences on social media influence people to (consider) not using social media? How might this influence differ for different sorts of regretful experiences? We adopted a mixed methods approach, combining topic modeling, logistic regressions, and contingency analysis to analyze data from a web survey with a demographically representative sample of US internet users (n=515) focusing on their Facebook use. We found that experiences that arise because of users' own actions influence actual deactivation of their Facebook account, while experiences that arise because of others' actions lead to considerations of non-use. We discuss the implications of these findings for two theoretical areas of interest in HCI: individual agency in social media use and the networked dimensions of privacy.","PeriodicalId":334195,"journal":{"name":"Proceedings of the 2018 ACM International Conference on Supporting Group Work","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133775508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
